Application iilerl March 26, 1901. Serial No. 52,951. (No modela To Ltr/ZZ 1071/0711/ 11m/y concer-7e:

Be it known that we, DELMER E. PRESTON and WILLIAM H. ATKINSON, citizens of the United States, and residents of Omaha, in the county of Douglas and State of Nebraska, have invented a new and Improved Scraper, of which the followingis a full, clear, and eX- act description. f

The invention relates to Scrapers used in ro pigsfeetcl`eaning and other machines; and

its object is to provide a new and improved scraper more especially designed for effectively and quickly cleaning pigs feet, pigs heads, and like articles and without requiring subsequent trimming with a knife and without danger of "cutting the article, the scraper being simple and durable in construction and not liable to wear out in a short time, as is the case with wire brushes heretofore con 2o structed and used for the purpose mentioned.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a reduced side elevation of the improvement with parts in section. Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. l. improvement with a head removed and parts shown in section. Fig. tis a transverse section of one of the scraper disks and blades, the section being on the line fi t in Fig. 3. Fig. 5 is a perspective View of one of the cushion-blocks. Fig. 6 is a face view of one of the 4o blades for cleaning a pigs foot between vthe toes, and Fig. 7 is an edge View of the same. The improved scraper is in the form of a wheel adapted to be rotated by suitable means and preferably forming part of a pigsfeet-cleaning or other similar machine, the arrangement being such that the article to be cleaned is moved lengthwise under the wheel by suitable feeding devices, or it may be held and moved under the wheel by an operator.

As shown in Figs. 1, 2, and 3, the wheel is Fig. 3 is a side elevation of the secured on a shaft A and is provided with a plurality of disks B B B2, on which are mounted scraper-blades C O O2, respectively, each blade having its inner end formed into apivot O3, set in a correspondingly-shaped recess in the face of the corresponding disk to allow the blade to swing. The shank C'L of each blade extends radially in an outward direction from the pivot O3, and the front end of said shankabuts against a shoulder B3, forming an integral part of the corresponding disk B, B', or B2, The shank O4 of each blade is pressed on the opposite side or back by a cushion-block D, of rubber or other suitable elastic material, and set with said shank in a recess B4, formed in the face of the corresponding disk B, B', or B2.

Each block D is preferably provided .at its inner end with an offsetor foot D' for holding the block against outward movement in the disk when the wheel is rotated, thus requiring no further particular fastening means to hold the block in position on a disk.

The outer ends of the 'scraper-blades C O are arranged in their respective disks B B so as to have a staggering relation to each other and are slightly curved in the direction of their length and of such width as to overlie each other in the path in which they travel when the wheel is revolved, as will be readily understood by reference to Fig. 2. The disk B2 is spaced from the disk B' by suitable washers E, and the outer ends of the blade C2 are narrow to readily enter between the toes of a pigs foot, and thereby properly clean the foot between the toes, it being understood that the other blades C C serve to more particularly clean the outer surface of the article. e

In order/tol hold the several disks B B' B2 in position, suitable heads F F or other devicesareemployed for the purpose.

It is understood thatthe head F engages the front face of the disk B and also the front faces of the shanks C4 and the pivots O3, while the back of the disk B engages the front face of the next following disk B and its blade O'. One of the washers E forms a front for the disk B2, so that the scraper-blades O C O2 are not liable to become disengaged from their corresponding disks.

When the device is in use and the wheel is rotated, then the cutting edges of the scraperblades cut olf any surplus material from the pigs feet or other articles under treatment, it being understood that when a scraper-blade strikes an obstruction or hard matter on the article then it readily yields in a backward direction against the tension of the corresponding cushion-block D, so that the obstruction is passed without cutting into the liesh of the article. When the wheel is in use, it rotates in the direction of the arrow a. (See Figs. l and 3.)

Having thus fully described our invention, we claim as new and desire to secure by Letters Patentl. In a scraper, a revoluble disk provided upon its circumference with a series of recesses, each of which comprises an undercut portion to aord anchorage, a blade inserted in each of said recesses, and a block provided with a tongue entering said undercut portion, said block being fitted into said recess against said blade.

2. A scraper, comprising disks provided with blades yieldingly mounted thereon, said blades being provided with vwidened operating edges, contiguous disks being so disposed that the blades of one disk alternate with the blades of another disk.

3. A scraper, comprising disks provided with blades yieldingly mounted thereon, said blades being provided with widened operatl ing edges, contiguous disks being so disposed that the operating edges of one disk project partially into the path of the operating edges of an adjacent disk, for the purpose of insuring action upon every part of the surface'to be scraped.

et. A scraper, comprising a revoluble disk provided with recesses in its edge and alsoin one of its faces, a blade provided with an enlarged head anchored in one of said recesses and extending radially outward from said disk, and a block mounted in the other of saidrecesses, for holding said blade.

5. A scraper, comprising a revoluble disk provided in one of its faces with cylindrical recesses and in its edge with L-shaped recesses, blades provided with pivotal heads for engaging said cylindrical recesses, and L-shaped blocks fitting said L-shaped recesses and engaging said blades.

6. A scraper, comprising a revoluble disk provided with outer recesses in its edge and also with inner recesses in one of its faces, said recesses communicating with each other, blades provided with pivotal heads entering said inner recesses and projecting radially through said outer recesses, and compressible members located in said outer recesses and pressing upon said blades for the purpose of rendering said blades yieldable.

7. In a scraper, a revoluble disk provided with recesses, from each of which extend undercutportions, ascraping-tool provided with an enlargement forming a pivotal connection in one of said undercut portions, and a resilient member located in said recess and engaging the other undercut portion, and yieldingly pressing against said scraping-tool, substantially as described.

8. A scraper, comprising a revoluble disk, provided with a plurality of recesses, from each of which extends a plurality of undercut portions, a scraping-tool inserted in each recess and provided with an integral part which forms a direct pivotal connection with one of said undercut portions, and a compressible member located in said recess and engaging the other undercut portion and resting against said scraping-tool, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
